How Security Window Film Works
3M Safety & Security Window Film is already protecting businesses, schools and homes across the country, including on the Gulf Coast, where we have installed it since 1973. Understanding how security window film works is simple: instead of trying to stop glass from breaking, it controls what happens after the break. Here’s how:
- The film and its strong adhesive form a protective membrane on the glass.
- The film is applied on the interior side of the window, which protects it from the elements and from direct attacks.
- While the film doesn’t protect the glass from breaking, it does help hold together the broken glass fragments.
- Film attachment systems are applied along the perimeter to anchor the film to the window frame.
- The film forces an intruder to create an opening through the center of the broken glass, which slows them down by up to 2 minutes and gives responders precious time.
3M Safety & Security Window Films provide:
- A deterrent against smash-and-grab burglars
- Safety glazing
- Seismic preparedness
- Protection against spontaneous glass breakage
- Blast mitigation
Security Window Film FAQs
Does security window film make glass unbreakable?
No. The glass still breaks, but the film holds the fragments together in the frame so there is no easy opening to climb through.
What do attachment systems add?
They anchor the filmed glass to the window frame around the perimeter. Combined with safety film, that bond delivers the highest level of protection 3M offers.
How much delay does the film create?
Forcing an opening through filmed glass can slow an intruder by up to 2 minutes, and every one of those seconds is response time. You can preview film options on your own glass with 3M’s window film simulator.
Where can I get 3M security film installed?
NBI Suncontrol installs 3M Safety & Security films for homes, businesses, and schools across Sarasota and Manatee County.
